确保未来粮食安全的需要和河口水质变化的问题正在推动水产养殖向近岸沿海沃茨扩展。在对基础设施和人员配置进行任何实质性的财政投资之前，对新的或拟议的水产养殖地点进行全面评估是谨慎的。水温、盐度和溶解氧的测量可用于深入了解养殖场内的物理、化学和生物水质条件，以确定其是否适合养殖，既可用于感兴趣的种群物种，也可用于评估有害或有毒藻类的潜在风险。后者可能导致贝类捕捞关闭。不幸的是，商业科学监测系统对于小型组织和公司购买和运营来说可能成本过高。在这里，我们描述的设计，建设和部署的低成本（<£ 5000）监测浮标适用于近岸水产养殖场或洗澡沃茨。系泊系统包括一套传感器，旨在支持和了解近岸物理，化学和生物水质的变化。该系统的设计使其可以由非科学人员操作和维护，同时仍然提供高质量的科学数据。从两个部署共14个月，一个在沿海海湾的位置，另一个在河口，收集的数据，说明了稳健的设计，并提供了深入了解这些网站的水产养殖和潜在的毒素引起的藻类（甲藻属）的适用性。与独立的原位测量值（例如RMSE 0.13-0.16 °C，偏差0.03-0.08 °C）相比，仪器在部署期间保持了良好的准确性，从而能够识别分层和生物特征，沿着确认沃茨适合贻贝（贻贝属）。和龙虾（Homarus gammarus）水产养殖，而网站显示条件适合甲藻属。
The need to ensure future food security and issues of varying estuarine water quality is driving the expansion of aquaculture into near-shore coastal waters. It is prudent to fully evaluate new or proposed aquaculture sites, prior to any substantial financial investment in infrastructure and staffing. Measurements of water temperature, salinity and dissolved oxygen can be used to gain insight into the physical, chemical and biological water quality conditions within a farm site, towards identifying its suitability for farming, both for the stock species of interest and for assessing the potential risk from harmful or toxic algae. The latter can cause closure of shellfish harvesting. Unfortunately, commercial scientific monitoring systems can be cost prohibitive for small organisations and companies to purchase and operate. Here we describe the design, construction and deployment of a low cost (<£ 5000) monitoring buoy suitable for use within a near-shore aquaculture farm or bathing waters. The mooring includes a suite of sensors designed for supporting and understanding variations in near-shore physical, chemical and biological water quality. The system has been designed so that it can be operated and maintained by non-scientific staff, whilst still providing good quality scientific data. Data collected from two deployments totalling 14 months, one in a coastal bay location, another in an estuary, have illustrated the robust design and provided insight into the suitability of these sites for aquaculture and the potential occurrence of a toxin causing algae (Dinophysis spp.). The instruments maintained good accuracy during the deployments when compared to independent in situ measurements (e.g. RMSE 0.13–0.16 °C, bias 0.03–0.08 °C) enabling stratification and biological features to be identified, along with confirming that the waters were suitable for mussel (Mytilus spp.) and lobster (Homarus gammarus) aquaculture, whilst sites showed conditions agreeable for Dinophysis spp.
